BOTTLE CLOSURE AND THE LIKE.

Application filed September 15, .1822. Serial No. 588,379.

The invention relates to closures of the type commonly used to seal milk and cream bottles or jars. A closure. of such type consists, ordinarily, of a thin disk of paper material, and in use fits within the mouth or neck of a bottle or jar upon an internal seat.

More particularly, the invention relates to closures of the type aforesaid of the class in which a closure has combined therewith means for facilitating the extraction of the closure from a container to which it has been applied.

The invention is in the nature of an improvement upon the extractor closure or cap of U. S. Letters Patent to Harris Moak granted under date of December 7, 1920, No. 1,361,394.

Special objects of the invention are to avoid certain drawbacks in connection with extractor closures or caps known prior to the present invention; to secure certain improved results: in connection with the extractor attachment; and to perfect the closures or caps for use in standard capping machines.

The features of the invention are illustrated in the drawings, in which latter,

Fig. 1 is an isometric view of an' extractor closure or cap embodying the said features.

Fig. 2 is a top view thereof.

Fig. 3 is a bottom view thereof.

Fig. 4 is a view in cross-section on line 4, 4, of Fig. 2.

Fig. 5 is a view in cross-section on line 5, 5, of Fig. 2.

In the drawings,-

1 is the thin disk, usually of paper material as aforesaid, constituting the bodyportion of a closure. No. 1,361,394, the extractor attachment shown applied to the disk 1 is made of wire, in hair-pin shape, with its handle-portion in the form of an open loop or bail extended inward toward the center of the disk from points 2, 2, where the twol mbs 21, 21, of the attachment pass down through the disk from the top to the bottom thereof. Continuations 22, 22, of the limbs extend outward from said points 2, 2, toward the disk-periphery, as in the Moak patent, but they do not reach to the disk-periphery as in the latter. At points 23, 23, slightly 1n- As in Moak Patent ward from the disk-periphery the extremities 24, 24, of the two limbs pass upward through the disk to its top surface, and are clinched upon' such surface, as shown in the same line with the limbs to which they respectively pertain.

The different ortions of wire at the top and bottom sur aces of the disk are impressed into the latter, as shown, so that the two surfaces are smooth and flat, facilitating stacking of a number of closures one upon another, and otherwise facilitating use of the closures in standard capping machines. Below the cross-piece 3 of the bail or closed loop a depression 4 is formed, which is bridged by said cross-piece as shown best in Fig. 4. The said depression enables a finger nail, or the end of a convenient tool, to be inserted under said cross-piece, and thereby facilitates the lifting up of the handle into position to be grasped and pulled upon for the purpose of withdrawing the closure from its seat in connection with a bottle or jar. The depression is made prior to the application of the extractor to the disk, whereby sinking and setting of the intermediate portion within the material of the disk so as to interfere with free picking up and lifting of the handle is avoided.

The shoulders or bends 5, 5, of the handle portion are bent down lower than theside arms or limbs 21, 21, and also lower than the intermediate portion bridging the depression 4, and are embedded deeply into the disk at opposite sides of depression 4 so as to safeguard against accidental dislodgement and lifting of the closed end of the handle, and thereby against catching of the handle asthe closure is moved edgewise in a capping machine. At the places where the shoulders or bends are embedded, the material of the disk is of the full thickness, 'so that such shoulders or bends are enclosed and shielded while the bridge remains relatively elevated, so as to permit of the ready insertion of a finger nail, orimplement, beneath the same. The side arms or limbs, 21, 21, are depressed only far enough to leave the top surface of the closure smooth and avoid catching of said portions, of the extractor in a ca machine or the like. The reason for sinking different portions of the extractor to different depths within the material of the disk is to avoid the cutting and weakening of the disk which would result from sinking all portions to the depth necessary in connection with the shoulders or bends.

The feature of assing the extremities 24, 24, of the limbs of the extractor attachment through the disk at points inward from the periphery of the disk greatly facilitates the manufacture of closures, inasmuch as thereby extremely delicate adjustment of machine parts employed for the manufacture are rendered unnecessary; extreme care does not have to be exercised to provide against the marring of the edge of the disk. Simpler and more common forms of mechanical appliances may be used in the manufacture. With the said extremities passed through the disk at points inward from the diskperiphery the said periphery is left unbroken and free from indentations in its edge to permit leakage of the contents of the bottle or jar. With the clinched extremities extending inward in line with the limbs of which the said extremities respectively form portions the operations by which the bending back and clinching of the said extremities. are performed are simplified and rendered more facile of performance, permitting also more simplified mechanism to be utilized 111 the closure-making machine.

What is claimed is:

l. A closure comprising a thin disk and an extractor attachment of hair-pin form, said attachment having an inwardly-extend ing bail-like handle with side limbs slightly embedded at the top surface; of the disk and relatively depressed opposite: shoulders embedded in portions of the; full thickness of the disk, and said disk having a depression between said embedded shoulders below an intermediate portion of the cross-bar of the handle.

2. A closure comprising a thin disk and an extractor attachment of hair-pin form, said attachment having an inwardly-extending bail-like handle with side limbs slightly embedded at the top surface of the disk and relative]. depressed opposite shoulders embedded in portions of the full thickness of the d sk, and said disk having a depression between said embedded shoulders below an intermediate portion of the cross-bar of the handle, said intermediate portion bridging the said depression at a higher elevation than the said shoulders.

In testmonv whereof I ailix my sianature.
